为了解粉煤灰掺量对泡沫水泥性能的影响，对掺粉煤灰泡沫水泥抗压强度、干燥收缩性、软化系数以及排水曲线进行了研究。试验结果表明，当粉煤灰掺量小于20%时，随着粉煤灰掺量的增加，泡沫水泥抗压强度与干燥收缩值均减小，软化系数在15%左右时最小。另外，试样的排水曲线可以采用可近似利用Boltzmann方程{y=A2+（A1-A2）/（1+exp（（x-x0）/dx））}来估计。

Objective to understand the effect of the content of fly ash on the property of foam cement,the effect of the content of fly ash on the property of foam cement was studied in detail by the compressive strength,dry shrinkage property and softening coefficient.The re-sults showed that:compressive strength and dry shrinkage property decreases with the increase of the content of fly ash.The softening coef-ficient was the least,when the content of fly ash was 15%.In addition,discharged water curve can be estimated by Boltzmann equation{y=A2+(A1-A2)/(1+exp((x-x0)/dx))}.
